Introduction

This user guide contains information on the preparation, operation and maintenance of the Thermo Scientific Orion ORP electrodes. These ORP electrodes combine a platinum redox sensing electrode and a silver/silver chloride reference electrode in one body.

The redox/ORP electrodes can be used to make direct measurements of redox potentials or perform potentiometric titrations. The ORP Triode electrodes have a built-in thermistor for measuring temperature.

Epoxy Sure-Flow Combination Redox/ORP Electrodes, Cat. No. 9678BNWP and 967800

The Sure-Flow junction prevents the electrode from clogging in dirty, viscous or wastewater samples. The epoxy body is break- resistant for rugged environments.

Glass Combination Redox/ORP Electrodes,

Cat. No. 9778BNWP and 9778SC

The glass body enables the electrode to be used in solutions that contain organic solvents. Use the electrode in water, wastewater, metal plating and organic solvent samples.

Epoxy Refillable ORP/ATC Triode,

Cat. No. 9180BNMD and 9180BN

The electrode includes a built-in temperature probe for measuring ORP and temperature with one electrode. The refillable design allows the electrode filling solution to be changed in case of contamination or clogging.

Epoxy Low Maintenance ORP/ATC Triode,

Cat. No. 9179BNMD and 9179BN

The electrodes include a built-in temperature probe for measuring ORP and temperature with one electrode. The electrodes contain a gel reference solution, so no filling solution is required.

Note: Redox/ORP electrodes are not designed for constant current or amperometric titrations, such as Karl Fischer moisture analysis.
